T 0 all whom it may concern:

Be it known that I,LOU1s KRIEQER, of 45 Boulevard Haussmann, Paris, France, on-

gineer, have invented a new and useful Imrovement in Motor Driven and Steered ore Carriages for Automobiles, which improvement is fully set forth in the following specification.

This invention relates generally to automobiles, and particularly to a novel form of axle sleeve movable about a )ivot placed-in a vertical line drawn througi the point of contact of-the wheel with theground in order absolutely to avoid any effect whatever u on the steering without the intermediary 0 any disconnecting or other switch in the electric circuits, should there be an inequality in the power of the driving motors, or should damage be done to one or both of them.

In opposition to-known arrangements of the same kind, this invention consists in obtaining the above'results by the combination of a pivot placed in the axle sleeve, which for this purpose is made hollow and is only capable of an angular movement about the pivot, with a'motor' affixed upon the axle sleeve and driving, through a single train of ,gearing, the hub of the wheel which is formed as an axle box and r'otates on the non-rotatable axle sleeve. This. arrangement is particularly' simple and light, and permits of easy and thorough lubrication, and also allows any suitable amount of dishing to'be given to the wheels.

The annexed drawing illustrates method of carrying out this invention. I

Figure 1 is a vertical section taken through the axis of the wheel. Fig. 2 is an outside front elevation ofthc same.-

The. wheel 1 is mounted upon a hub 2 which turns upon the axle sleeve 3 with two rings of balls 4 and 5. This hubcarries a gear wheel 6 which receives movement from the inion 7 of the motor 8. fixed and takes-part to ether with the said sleeve in all the angular steering movements. This axle sleeve also carries the coupling arms 9 of the steering arrangement and is connected to the axle 10 by a pivot 11 provided with two rings of balls 12 and 13 the axis of the pivot is vertical and passes The motor is by a lugand bolts to the axle sleeve 3 throu h the theoretical point of contact of thew eel with the ground- A casing 14 incloses the train of gearing. By this arrange ment there is no movement in a horizontal plane of the lever arm with respect to the pivot due to the reactions caused b. v the "ariations in the strain upon the pinion of the .motor, these reactions cannot therefore infiuence the steering.

Claim 1. In a vehicle, the combination, with an axle, and an axle sleeve pivoted to the axle and provided with hub-bearings at each side of the pivotal point, of a wheel having a hub journaled upon the said hub-bearings, a n10- tor carried byflthe axle sleeve, and gearing intermediate the wheel and motor whereby the wheel is driven.

2. In a vehicle, the combination, with an axle, andan axle sleeve arranged to inclose the end of the said axle, of a wheel mounted upon the axle sleeve, bearings intermediate the wheel hub and axle sleeve at each side of the wheel, a pit'otpin connecting the axle and axle sleeve and having its axis in a vertical-line through the theoretical point of contact of the wheel withthe ground, a motor supported by the axle'sle'eve, and gearing between the motor and wheel whereby the wheel is driven.

3. In a vehicle, the combination, with an axle having a vertical pivot socket in its end, of an axle-sleeve inclosing the end of .the axle and provided with hub-bearings at each side of said pivot-socket, a hub attached to the 'wheel and mounted on said huh-bearings, a

specification in the presence of two subscribing witnesses.
